METHOD TO OPERATE REFRIGERATING UNIT, COMPRISING PARALLEL JOINED EVAPORATORS, AND REFRIGERATING UNIT Russian patent published in 2012 - IPC F25B5/02 F25D11/02 

FIELD: heating.

SUBSTANCE: refrigerating unit is arranged with a refrigerating contour (15) comprises two parallel arranged evaporators (16, 17), and also with a compressor (22). Evaporators (16, 17) cool refrigerating chambers (12, 13), which are thermally separated from each other. The compressor (22) is arranged as capable of supplying a coolant into both evaporators (16, 17) separately from each other. In case of demand for cold in the first of the chambers (12, 13), with a higher temperature, at the preparation stage at first the coolant is supplied, at least, into the evaporator (17, 16) of the second chamber (13, 12) having lower temperature. Then the refrigerating contour to this evaporator (17, 16) is closed, and the coolant is supplied to the evaporator (16, 17) of the first chamber (12, 13), having higher temperature. The preparation stage is in process until work done by the compressor (22) exceeds the limit value, or the compressor (22) efficiency exceeds the limit value.

EFFECT: invention provides for simple and efficient operation of a refrigerating unit.
